Notes

Studio recording, 1975. Jerry Garcia's 'Wolf' guitar was used on the studio version of 'Franklin's Tower' (Blues for Allah, 1975). The amp setup was his classic Fender Twin Reverb preamp into a McIntosh MC2300 power amp, with the Mu-Tron III envelope filter as a key effect. No evidence of distortion/overdrive pedals; the driven tone is from amp and picking dynamics. Pickup selection likely bridge or middle for solo brightness.

Difficulty

The solo requires intermediate to advanced phrasing, dynamic picking to control the envelope filter, and clean execution of syncopated melodic lines. The technical challenge lies in expressive timing and effect control rather than pure speed.
